GEROtherm® DUPLEX-RTThe geothermal probe for greater temperature and stress crack resistance made from PE100-RT-RC*

Principle:


Double-U probe for shallow geothermal use. Resists internal pressure up to PN16 at 20 C and PN20 at 20 C. The probe pipes have the same outside diameter as the DUPLEX double-U probes, but are made from PE100-RT-RC*.

Design:‎


The probe foot (U-bend) is an important component in the GEROtherm® geothermal probe. It is subjected to the greatest stresses during installation and operation. That is why HakaGerodur has modified and patented its tried-and-tested GEROtherm® probe foot (32 mm and 40 mm). It is made from the material E100-RT-RC*.

* Geothermal probes made from PE100-RT-RC is a protected technology. Patent No. CH 717 800 A2.

1) The expected durability of the material depends on the duration and temperature of use, along with the inside pressure. The load limits are calculated based on the cumulative damage rule (Miner’s rule) as per SN EN ISO 13760. (For an object-specific definition, the annual frequency temperature profile and the inside pressure must be provided.)
